IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent NO. 142,850, datedSeptember 16, 1873 application filed March 1, 1873.

To all whom it may concern:

Be it known that I, JAMES HENRY HILL, of Boone, in the county of Dallasand State of Iowa, have invented a new and Improved WashingMachine, ofwhich the following is a specification:

My invention consists of a rectangular tub with corrugated or ribbedbottom and sides, mounted on trunnions at the sides on a suitable stand,so as to oscillate in its longitudinal plane, with several loose ballsof wood placed in it on the clothes to act in conjunction with the waterto eEect the washing of the clothes, the tub being oscillated or swungon its trunnions by the attendant to cause the necessary motion of thewater, balls, and clothes.

Figure l is a longitudinal sectional elevation of my improved machinetaken on the line x of Fig. 2, and Fig. 2 is a transverse section takenon the line y y of Fig. 1.

Similar letters of reference indicate corresponding parts. fgtgArepresents the rectangular tub, with ribbed or corrugated sides B andbottom C, and mounted on the journals or trunnions D, in a stand, E, sothat it balances and can be readily swung or oscillatcd vertically inits longitudinal plane to agitate the water and cause the -necessarymotion for effecting the washing by the balls F of wood, which areplaced in the tub with the clothes; also, by the rubbing of the clothesalong the bottom and sides of the tub. A cover, G, is fitted on the top,and fastened down tight to prevent the water from slopping out, and ahooked brace, H, is provided to hold the tub against swinging when theclothes are being put :in or taken out; also while the wringer is used,which is clamped on the top of the tub.

While I prefer a tub of rectangular form, I do not limit myself to it;but propose to avail myself of suitable or equivalent form. This plan Iconsider more simple, economical, and efiicient than any other now inuse.

Havin g thus described my invention, I claim as new and desire to secureby Letters Patent- The combination of an oscillating tub, A, and looseballs F, the tub having corrugated sides and bottom, substantially asspecified.

JAMES HENRY HILL.
